mkisofs creates iso images that get "Incorrect CD-ROM detected" error

[Dan Rolsma]

To reproduce, install Oneirc or Natty, from the desktop or alternate iso, 64 or 32 bit, created 10/23/2011 or later. If earlier apply updates released since 10/23/2011 (not reproducible on Natty or Oneirc install prior to Oct 19). Make an iso according to the InstallCDCustomization Community Documentation. These are my exact commands from that documentation on a fresh install:

mkdir iso
sudo mount -o loop ubuntu-11.10-alternate-amd64.iso iso
sudo mkdir /cd-image
sudo rsync -a iso/* /cd-image
cd /cd-image
sudo mkisofs -r -V "My Install CD" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -boot-load-size 4 -no-emul-boot -boot-info-table -o ~/my.iso .

Now boot from the my.iso in a VirtualBox, or make a CD and boot from that, and you'll get "Incorrect CD-ROM detected" about a minute into the installation, right after "detecting hardware to find CD-ROM drives" occurs in the installation. You can also try using usb-creator-gtk to make a bootable usb stick, but it won't accept the .iso image. No error msg, it just won't show it as selectable after clicking "Other ..." and opening it.

I had the same problem. I forgot to copy the hidden directory .disk from the cd. From the commands you posted this might be the same problem,

Where can I find the InstallCDCustomization Community Documentation?

The page has the following on it:

'Be sure to catch the folder .disk - if you try and copy /cdrom/*, it will ignore the .disk folder, as Bash expands the * to mean "everything it can see".'

[Dan Rolsma (dan-rolsma)]

In my rsync command I specified directory names so all the files get copied, at least that has been my experience with rsync.

[Dan Rolsma (dan-rolsma)]

Whoops, I did use the *. Hmmm, that may explain it. I'll have to retry with:

sudo rsync -a iso /
cd /iso

and see what happens.
